If someone is inadmissable to USA but has a direct flight from Vancouver to Mexico over US airspace are they able to fly.
I know about the noflylist which is not the issue.
But otherwise it shouldn't be a problem right?
Flying to mexico US airspace
@Akrab Great question but the answer is they will have no problem.
If you have a connecting flight? Problem.
I agree with J Rogers
Should be no problem if you are not connecting.
Just flying over USA airspace is no issue as long as you are not on the Nofly list.
Someone was deported after finishing their sentence in USA (narcotics) and has no issue.
Good luck
